Munyika yekushandiswa kwedata uye kuongorora, kubata hunhu husipo ibasa rakakosha. pandas, raibhurari yePython inoshandiswa zvakanyanya, inotibvumira kubata nemazvo data yakarasika. Imwe nzira yakajairika yekubata nehunhu husipo inosanganisira kushandisa maduramazwi kumepu nekutsiva izvi zvakakosha. Muchinyorwa chino, tichakurukura maitiro ekuwedzera simba rePandas nePython kushandisa maduramazwi ekutsiva nhanho dzakashaikwa mudhata.
Python
Pane zvishoma zvekusuma kuPython. Inonyatsozivikanwa nevagadziri vese.
Chese chaunoda chinogona kuitwa nePython uye izvi, pamwe nekureruka kwayo uye nyore, zvaita kuti ive imwe yemitauro yekuronga nyeredzi nhasi. Mutauro wakanyatsotaipa chinhu-unonyanya kukosha kuchengetedza kuverenga kwekodhi.
Ndiwo mutauro wenyeredzi musainzi yedata, kudzidza kwemichina, kudzidza kwakadzama, uye zvese zvine chekuita.
Asi iwe unogona zvakare kuvaka webhu maapplication, kana chero chimwe chishandiso chaungafunga nezvacho.
Kune zvitoro zvemabhuku zvezvose !!!
Muchikamu chino tinogadzirisa mamwe ematambudziko makuru ayo mugadziri wePython anowanzo kutarisana nawo. Nenzira iyi nzira yekuve ninja dev mupython inovimbiswa.
Yakagadziriswa: maitiro ekusiya mazuva pandas datetime
Mafashoni uye hurongwa zvingaite senyika mbiri dzakasiyana zvachose, asi kana zvasvika pakuongororwa kwedata uye kufanotaura kwemaitiro, vanogona kuuya pamwechete. Muchinyorwa chino, isu tichaongorora dambudziko rakajairwa rekuongororwa kwedata muindasitiri yemafashoni: kusiya mazuva chaiwo kubva papandas datetime data. Izvi zvinogona kunyanya kubatsira kana uchiongorora mapatani, maitiro, uye data rekutengesa. Tichapfuura nenhanho-ne-nhanho tsananguro yekodhi, uye tokurukura maraibhurari akasiyana-siyana uye mabasa ayo achatibatsira kuzadzisa chinangwa chedu.
Yakagadziriswa: tafura pandas kune postgresql
Munyika yekuongorora data uye kunyengera, imwe yeanonyanya kufarirwa Python maraibhurari ndeye pandas. Inopa akasiyana maturusi ane simba ekushanda nedata rakarongeka, zvichiita kuti zvive nyore kushandura, kuona uye kuongorora. Rimwe remabasa mazhinji angasangana nemuongorori wedata kupinza data kubva kune a CSV faira mu a PostgreSQL database. Muchikamu chino, tichakurukura maitiro ekuita basa iri nemazvo uye nemazvo tichishandisa ese ari maviri pandas uye psychopg2 library. Tichaongororawo mabasa akasiyana uye maraibhurari anobatanidzwa mukuita uku, tichipa kunzwisisa kwakadzama kwemhinduro.
Yakagadziriswa: pandas akateedzana anowedzera izwi kuchinhu chimwe nechimwe munhevedzano
Pandas iraibhurari ine simba uye inochinjika muPython, inowanzoshandiswa kugadzirisa data uye kuongorora mabasa. Chimwe chezvinhu zvakakosha mukati mePandas ndeye Series chinhu, icho chinoumba one-dimensional, yakanyorwa array. Muchinyorwa chino, isu tichatarisa pane chaiyo dambudziko: kuwedzera izwi kune chimwe nechimwe chinhu muPandas Series. Tichafamba nemhinduro, tichikurukura kodhi nhanho nhanho kuti tinzwisise kushanda kwayo kwemukati. Pamusoro pezvo, tichakurukura nezvemaraibhurari ane hukama, mabasa, uye nekupa ruzivo mumatambudziko akafanana.
Yakagadziriswa: wedzera akawanda makoramu kune dataframe kana isipo pandas
Pandas iraibhurari yakavhurika-sosi yePython inopa kushanda kwepamusoro, nyore-kushandisa-data zvimiro, uye maturusi ekuongorora data. Yakave sarudzo yekuenda kune vanogadzira uye data masayendisiti kana zvasvika pakubata data uye kuongorora. Chimwe chezvinhu zvine simba zvinopihwa nePandas kugadzira nekugadzirisa dataframes. Muchikamu chino, tichaongorora maitiro ekuwedzera akawanda makoramu kune dataframe kana isipo, tichishandisa pandas raibhurari. Isu tichafamba nenhanho-ne-nhanho tsananguro yekodhi uye kunyura mumabasa ane hukama, maraibhurari, uye matambudziko aungasangana nawo munzira.
Yakagadziriswa: isa akawanda columns pandas
Pandas iraibhurari ine simba uye inoshanda zvakasiyana-siyana yePython inoshandiswa zvakanyanya pakugadzirisa data uye kuongorora. Chimwe chinhu chinodiwa kana uchishanda nedata kuisa akawanda makoramu muDataFrame. Muchinyorwa chino, tichaongorora maitiro ekuwedzera akawanda makoramu kuDataFrame uchishandisa iyo Pandas raibhurari, kurukura kodhi, uye kunyura zvakadzika mumabasa ane hukama, maraibhurari, uye pfungwa dzinogona kukubatsira iwe kuve nyanzvi yePandas.
Yakagadziriswa: kuwana huwandu hwekushaikwa kwakakosha mumapanda
Pandas inoshandiswa zvakanyanya yakavhurika-sosi data manipulation raibhurari yePython. Inopa zvimiro zve data uye mabasa anodiwa kuti anyatso shandisa uye kuongorora mahombe dataset. Rimwe dambudziko rakajairika data masayendisiti uye vanoongorora vanosangana vachiri kushandisa pandas kubata hunhu husipo mudhata. Muchinyorwa chino, isu tichaongorora maverengero ehuwandu hweakashaikwa muPandas DataFrame tichishandisa akasiyana matekiniki, nhanho-ne-nhanho tsananguro dzekodhi, uye kuzama zvakadzama mune mamwe maraibhurari nemabasa anobatanidzwa mukugadzirisa dambudziko iri.
Yakagadziriswa: shandura timestamp kuita nguva pandas
Munyika yanhasi, kushanda nenguva-yakatevedzana data inyanzvi yakakosha kune mugadziri. Rimwe remabasa akajairwa nderekushandura timestamp kune yakatarwa nguva, senge data revhiki kana remwedzi. Kuvhiya uku kwakakosha pakuongorora kwakasiyana, sekufunda maitiro uye mapatani mune data. Muchinyorwa chino, isu tichaongorora maitiro ekushandura timestamp kuti ive nguva mune yenguva-yakateedzera dataset uchishandisa ine simba Python raibhurari, Pandas. Tichatorawo kunyura mukati mekodhi, kuongorora maraibhurari nemabasa anobatanidzwa mukuita, uye kunzwisisa kukosha kwavo mukugadzirisa dambudziko iri.
Pandas ndeye yakavhurika-sosi data yekuongorora uye manipulation raibhurari, iyo inopa inoshanduka uye yakakwirira-kuita mabasa ekushanda nenguva-yakateedzera data. Inoita kuti basa redu rive nyore, rakarurama, uye rishande.
Yakagadziriswa: sefa makoramu ese mumapanda
Munyika yekuongorora data, kubata dhatabhesi hombe kunogona kuve basa rakaoma. Chimwe chezvikamu zvakakosha zvechiitiko ichi kusefa data kuti uwane ruzivo rwakakodzera. Kana zvasvika kuPython, raibhurari ine simba pandas anouya kuzotibatsira. Munyaya ino tichakurukura sei kusefa makoramu ese mupandas DataFrame. Tichapfuura nenhanho-nhanho tsananguro yekodhi uye kupa kunzwisisa kwakadzama kwemaraibhurari uye mabasa anogona kushandiswa kune mamwe matambudziko.
